Abstract
A surgical tool includes a driven portion, a cord-shaped element, and a rotor. To the driven portion, a driving force is transmitted from an external portion. The cord-shaped element transmits a movement of the driven portion. The rotor has a circumferential surface around which the cord-shaped element extending from the driven portion is wound. The circumferential surface includes two or more grooves arranged side by side in a direction of a central axis of the rotor so that the cord-shaped element is windable therearound, and at least one cut-out portion connecting adjacent grooves among the two or more grooves so that the cord-shaped element is placeable through the adjacent grooves.
